Referring more particularly to the drawing, in which the same parts aredesignated by the same reference numerals in all of the figures,

-the invention includes generally a channel hanger bar I, a pair ofbrackets 2, apair of spring locks 3 for detachably locking the ends,respectively, of said hanger bar to said brackets, and clamps 4 fordetachably clamping one or more cables, pipes, conductors and the likeof various sizes in position on said hanger bar I.

The channel hanger bar I is formed with a base wall 5 and a pair of sideWalls 6 depending from the side edges. respectively, of said base wall,and said base wall 5 is provided with a plurality of spaced paralleltransverse slots l.

Each of the brackets 2 is formed with a-supporting flange B at itslowerend, extending at right angles to the bracket and in a horizontalposition when the bracket is secured in a vertical position, upon whichanges 8 of said brackets rest the ends, respectively, of the base wall 5of the hanger bar I, whereby said bar is supported by said brackets uponsaid anges. Other supporting iianges 9 for the hanger bar I are securedon the brackets 2 above said supporting flanges 8, respectively, atsuitable elevations, for supporting said hanger bar at elevations abovethe supporting flanges 8. The brackets 2 are welded or otherwise securedat their upper ends to the under side of the deck of a ship or to theceiling or wall of a building, or to anyother suitable support. Theflanges t and 5l` are provided with slots I0 and II, respectively, whichslots extend transversely with relation to the brackets 2.

Each of the spring locks 3 comprises a single piece of resilient wireI2, preferably of steel, which wire is bent intermediate its ends at twopoints I3 and I 4, into an intermediate memrber I5 and a pair of springlocking arms I6 and Il extending from said bends I3 and I4,

respectively. The arm I6 is bent inwardly intermediate its ends at I8and outwardly from said bend I8 into an outward end extension I9. Thearm I'I is bent rst inwardly at 2|), then outwardly at 2I, and inwardlyin the form of an elongated outwardly-bowed inward cam extension 22. Theends ofthe base wall 5 of the hanger bar I are placed upon thesupporting anges 8 of the brackets 2, respectively, with slots I at theends of said base wall 5 in register with the slots I0 in saidsupporting vflanges 8, respectively, and the arms I6 and l1 of twospring locks 3 are introduced through the slots 'I at the ends,respectively, of the base Wall 50i the hanger bar I and through theregistering slots I0 in the supporting anges 8, respectively, upon whichthe ends of the hanger bar are supported, whereby the ends of the hangerbar are locked in supported position 3 on said supporting flanges 8, asshown in Fig. 3 of the drawing.

Each of the clamps 4 comprises a flexible clamp strap 23, preferably ofthin steel, and a clamp locking keeper 241. The clamp strap 23 ispreferably a strap of thin flexible steel, which may be wound andsupplied in rolls 25 to be cut off in suitable lengths by snips, to beused in clampsl of various sizes. The clamp keeper 23 comprises a bar26, preferably of sheet steel, bent downwardly and inwardly at a slightangle at one side into a side ange 21, from the outer edge 28 of whichflange, intermediate its ends, extends a short tongue 23, on the outerend of which tongue are formed a pair of spring arms 3G, extending inopposite directions from said tongue parallel to said flange 21, theendportions of which arms are bent outwardly therefrom in the form ofcatches 3| for engaging the side edges of the clamp strap, in the mannerand for the purpose hereinafter more-fully described.

The keeper bar 26 is provided with-a longitudinal slot 32 intermediateits ends to receive the clamp strap 23 to be locked by and between thecatches 3| on the spring arms 30 of the keeper 24, in the manner and forthe purpose hereinafter more fullyl described.

The operation of the invention is as follows:

The brackets 2 being secured in position at their upper ends to theunderside of the deck of a ship or to a ceiling of a building, orelsewhere, a hanger bar I is placed between a pair of said brackets withthe ends of the base wall 5 of said bar resting upon the supportingflanges 8 of said brackets, respectively, and with the transverse slotslat the ends of said base wall in registration with the slots I in saidsupporting flanges 8, respectively; the arms I6 and I1 of a spring lock3 are compressed towards each other, and the extensions I9 and 22 ofsaid arms, respectively, are introduced through each end slot 1 in thebase member of the hanger bar I and through the slot I0 of thesupporting ange 8 of each of said pair of brackets 2, as shown in Fig. 6of the drawing, and upon pressing down each spring lock the extension I9of the lock arm I6 is projected under the supporting flange 8 at one endof its slot I0, while the bowed cam extension 22 of the spring lock 3,engaging the adjacent end of the end slot 1 in the end ofthe base member5 compresses the arm I1 of said lock inwardly, until the bend 2| in saidarm passes through the adjacent ends of said' slot 1 of the hanger baseWall 5 and the slot I0 in the supporting flange 8, whereupon the arms I6and I1 of the lock 3 spring outwardly until the ends of the slots 1 andIll receive and are engaged by the bends I8 and 20 of the arms I6 andI1, respectively, of the lock 3, as shown in Fig. 3' of the drawing,thus holding the arms of said lockin the slots 1 and I0 and locking theends of the hanger bar I to the bracket flanges 8 supported in positionupon said flanges.

The cables, pipes, conductors, or'the like, indicated 33, being laidacross and upon the base wall 5 of the hanger bar I, a clamp strap 23 iscut at a suitable length from the roll 25 and placed around the upperside of one or more of said cables, or the like, and the ends of saidstrap are extended downwardly through two of the nearest slots 1 in thehanger base wall 5; one end of said strap is bent and extended upwardlythrough another slot l in said base wall 5 and between the cable or thelike and thestrap, or between the cable or the like and the upper sideofsaid hanger base wall 5; the other end of the strap 23 is then extendedthrough the slot 32 in the bar 26 of the keeper 24, from the outer sideof said bar, with the keeper 24 extended across the under side of thehanger bar I; the keeper 24 is then moved upwardly on the strap 23,which passes through the keeper slot 32, until the keeper bar 26 engagesthe lower edges of the side walls 8r of the hanger bar I, whereupon thekeeper is turned downwardly and upwardly clockwise (Fig. 1) until thekeeper ange 21, with its outer edge 28, engaging the lower edges of theside walls 6 of the hanger bar I as a pivot, is turned to an upstandingposition, during which operation the strap 23, with its keeper endextending through the keeper slot 32 and bent against the inner side ofthe keeper bar 26, is drawn down taut against the cable or the like 33by the keeper, the other end of the strap being held clamped between thecable and the strap, or between the cable and the hanger base wall 5,while the spring arm catches 3l are moved forwardly over the side edgesof the strap 23 under spring pressure of the spring arms 30 against saidstrap edges, until said catchesv are sprung inwardly by said arms andsnapped into engagement with the outer side of the clamp strap 23, thuslocking, the clamp strap in position clamping the cables or the like 33upon the base wall 5 of the hanger bar I in position for use.

The keeper 25 when in its locking position effectively clamps the cablesand the like in position on the hanger bar and will remain securely inits locking position until it is turned out of such position by asuitable tool.

The hanger bar I- will remain locked in position on the-supportingflanges 8 of the brackets 2, until the spring locks 3 are-compressed andthe arms I6 and I1- of said locks brought suiiciently close together andwithdrawn from the-slots 1 and I0, respectively, in the hanger bar I andthe supporting flanges 8, inthe reverse order in which said locks areintroduced into said slots.
